Experiment to demonstrate Moll’s half-leaf experiment for showing that CO 2 , light, chlorophyll and water are necessary requirements for photosynthesis: Requirements: A potted plant, caustic potash, wide- mouthed bottle, iodine, split cork, water Method: 1. De-starch a potted plant by putting it in complete darkness for two days. 2. Fill partly a wide-mouthed bottle with strong solution of caustic potash and fit a split cork on its mouth. 3. Insert about half of the portion of a leaf of the de-starched plant into the bottle through the split cork (Fig. 36). 4. Place the whole apparatus in light after applying grease on the upper portion of split cork, and test the leaf for stach after about 10 hours. Observations: Portions of the leaf inside the bottle as well as in between the split cork show negative test for starch indicating the absence of photosynthesis while the portions outside the split cork show positive test for starch indicating the presence of process of photosynthesis in

EUTROPHICATION

May 24, 2021

When water bodies such as lakes, estuaries and slow moving streams receive excess nutrients ,it results in excessive plant (algal) growth . This process is called eutrophication. This excessive growth of plants such as Water hyacinth and algae reduces the dissolved oxygen (BOD- biological oxygen demand) in water. The water body then becomes incapable of supporting fishes and other forms of aquatic life. Excessive growth of algae in such water bodies is described as algal bloom. Nitrates and phosphates are the two main substances(nutrients) that causes such condition, which is a direct result of pollution. These nutrients come from a variety of sources,such as fertilizers applied to agricultural fields and golf courses, excessive use if detergents, erosion of soil containing nutrients,untreated sewage and discharges from sewage treatment plants. EUTROPHICATION not only leads to reduced oxygen but also produce foul odour and slow death of water body. Thus, biodiversity in t

TYPES OF RESPIRATION

September 11, 2020

Respiration is a process by which the food gets oxidised to produce energy . There are different organs involved in this process in different organisms such as lungs , skin ,gills ,trachea, etc . Hence there are different types of respiration in living organisms depending on the organs involved . Branchial respiration : The respiration in which gills are used as organs of respiration is called branchial respiration. Ex. Fishes , they have special structures called gills for exchange of gases . Tracheal respiration: The respiration in which trachea are used as organs of respiration is called tracheal respiration.Ex. Insects ,they have small holes on either side of their bodies called spiracles . These spiracles opens up in tubes called trachea where exchange of gases takes place. Cutaneous respiration: If the respiration takes place through the skin then it is called cutaneous respiration. Ex . Frogs and other amphibians undertake two organs for their respiration . The skin and t
